State Sen. Johnny Key has vacated his seat in order to coordinate lobbying efforts for the University of Arkansas system as the associate vice president for university relations.

Gov. Mike Beebe will not call a special election to fill the empty seat due to the expected costs and logistical hurdles of replacing Key, whose term ends in January 2015.

Scott Flippo won the Republican nomination for the District 17 seat in June and will not have a Democrat challenger in the November election.
